llNiTnD STATES RICHARD M. GELINAS, OF SEATTLE, lVASHlNGTON, ASSIGNOR OFONE-HALF TO THOMAS F. COLBERT, OF SAME PLACE.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 590,974, dated October5, 1897.

Application led December 16, 1895. Serial No. 572,364. (No model.)

t provide an easy method of filling lubricators and one by which t-hespilling or Vwasting of any oil may be prevented; second, to avoid theconducting of a steam or condenser pipe through the oil in thelubricator, and thereby zo to prevent the heating or changing thetemperature of the oil, and thereby to avoid any interference with thetransmission into the steam-supply pipe of the amount of oil desired;third, to avoid the frequent delay after filling in again putting thelubricator into operation, and, fourth, to avoid the frequent and usualnecessity, in the ordinary lubrica` tor, after filling, of resetting thefeed or again regulating the amount of oil to be transmitted. l Theseobjects are attained by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is an elevation of my device, and Fig. 2 isa central longitudinal sectionof the 3 5 same.

Similar letters of reference refer to similar parts in both the figures.

The lubricator consists, in the first place, of a large central cylinderor cup A, as a re- 40 ceptacle for the oil, and having a rounded orbell-shaped cap F at the top, and which is to be removed when thecylinder is to be filled. This cap is not screwed on and is removedmerely by lifting. At the upper part of the cylinder and on the inside,at a point S just below where the cup is adjusted to the cylinder, is a'strainer for the keeping of dirt or dust from the oilbeneath. Joining onthe cylinder at the bottom is a condenserglobe L, and projectingdownward from this is a drain-cock G, by means of which the water may-be drawn from the condenser- `globe. Connected with said globe is apipe known as the condenser-pipe7 K, in which is a valve D, whichrespectively transmits and regulates the transmission `of the steam orwater into said globe. At one side and projecting from the centralcylinderA is a gage glass tube R for determining the amount of oil inthe cylinder, and at another side of 6o said cylinder is a sight-tube Nfor gaging the transmission of the oil from the cylinder into a pipe O,leading` into the steam-supply pipe B. In the interior of the cylinder,running lengthwiseV and from a point a little below the strainer S andvalve-seats of the oompression-valve-hereinafter mentioned, is stillanothertube M, which extends to the bottom of the cylinder and connectswith a short pipe leading to the aforesaid sight-tube'N. 7o In thisshort tube just mentioned, between said cylinder and said sight-tube andmidway therein, is a feed-valve P for the regulating of the amount ofoil to be transmitted through said sight-tube and into said steamsupplypipe B. Finally, and in the interior of the cylinder, and one of themost distinctive features of this invention, andextending when raisedfrom the top of the condenser-globe to nearly the top of the cylinder 8oproper and to a-'point V V a little above the top of the tube M and justbelow where the cap iits on the cylinder, is a compressionvalve H. Thisvalve consists of three partsthe valve proper, H', the stem H2, and the85 hollow bell-shaped piston H3. This piston slides in the neckconnecting the condensation-chamber with the oil-reservoir. The upper orclosed end of the bell is perforated by holes 71, to allow the water ofcondensation 9o 4 IOO valve leaves at V V or at S a wide opening thecondenser-globe L. The seats of this valve resting for the most part inoil wear out only with difficulty. A plug C closes the pipe O where itjoins the reservoir A.

The manner of operation is as follows, to wit: Close valve E, so as-toprevent the back pressure from the steam-pipe; then turn or close thevalve D in the condenser-pipe, thus preventing any transmission ot'steam or water from there into the condenser-globe L; remove the cap Ffrom the top of the cylinder; open the drain-cock G, so as to allow thesteam and water which has gathered in the globe to run out, and thevalve H, no longer supported by the water or steam, to drop and thusleave the cylinder open,as indicated at the top and at the points V; nowclose the cock G below the condenser-globe L and pour the oil in at thetop of the cylinder until filled; replace the cap F; now open the valveD in the condenserpipe, and the steam and water rushing into the globewill force the valve H upward; then open the valve E in theoil-transmitting pipe O and the oil will begin to iiow from the cylinderdown the tube M through the valve P into and through the sight-tube Ninto the steam-transmitting pipe O and supply-pipe B, whence it istransmitted to the cylinder or engine,l and the lubricator will be infull operation. The oil being lighter than water remains, of course,always on top in the cylinder, and as the condensed steam or watergathers in the condenser-globe in increasing quantity and rises into thecylinder and in the direction indicated by the arrows in Fig. 2 the oilis forced upward, together with the valve H, and the oil is forced downthe tube or pipe M, and so on, as indicated above.

By my invention the ordinary method of filling lubricators by theremoval or unscrewing of a plug and pouring oil through a small apertureis done away with, thereby avoiding not only considerable annoyance butalso the frequent leaking incident to said plugs. Having practically thewhole top of the cylinder into which to pour the oil renders anyspilling or wasting impossible.

By my plan of having the condenser-globe at the bottom of the lubricatorinstead of at the top, as in other lubricators, there is furtheravoided, as before suggested, the presence of a heated condenser-pipefrom a point above the lubricator down through the oil to the bottom ofthe cylinder. Consequently also, is there avoided the heating andsometimes boiling of the oil from contact with said pipe, andconsequently, also, any interference with the regular transmission orfeeding of the oil, a result that always follows any considerable changein its temperature.

\Vith my lubricator it is never necessary to wait for the oil to cooland the lubricator to operate, as the oil always remains at about thesame tei'nperature. By my device of a valve E in the oil-transmittingpipe O all back pressure of steam from the steam-Supply pipe B isavoided. In other lubricators this back pressure is prevented byshutting the feed-valve P, which, however, necessitates time and troublein resetting the same when again ready for operation. The avoidance ofthis is also a distinct ad vantage of my invention over others, forafter having once set the feed-valve so as to provide for thetransmission of the requisite drops of oil per lhour no furtherattention to the same is necessary.

Having fully described my invention, what I therefore claim, and desireto secure by Letters Patent, is-

1. In a lubrica'tor, the combination with an oil-reservoir havingafilling-opening in its upper end, a condensation-chamber connected toits lower end by a neck and a steam-pipe connection to saidcondensation-chamber, of a plungeror valve within said reservoir adaptedwhen raised to close said filling-opening, a stem connected to the valveand a bell-shaped piston connected to the lower end of the stern so asto slide in the neck of the condensationchamber and having perforationsthrough its upper end, substantially as shown and described.

In a lubricatorwith an oil-reservoir open at its upper end and having aninternally-facing valve-seat just below the upper end,acondensation-chamber connected to the lower end of the oil-reservoir bya vertical neck, and a steam-pipe connection to thecondensationreservoir, of a valve within said reservoir adapted to beraised by the steam-pressure and consisting of the valve proper, adependent stein and a bell-shaped piston on the lower end of the stemadapted to slide in the neck of the condensat-ion-chamber and havingperforations in its upper end, substantially as shown and described.

3. In a lubricator, the combination of an oilreservoir having afilling-opening at its upper end, a condensation-chamber at its lowerend, a steam-pipe connection to said condensationchamber, a valve withinthe reservoir adapted to be held closed by the steam-pressure a guideand perforated piston sliding therein located between thecondensation-chamber and oil-reservoir, said piston being connected tothe valve to close the same, substantially as shown and described.
